Rabbit EphA4 Polyclonal Antibody | anti-EphA4 antibody

EphA4 (Tyr-602)[conserved site], phospho-specific Antibody

Cat. Num. AAA71630

• Gene Names: EPHA4; SEK; HEK8; TYRO1
• Reactivity: Human, Rat, Mouse, Chicken
• Applications: Immunohistochemistry, ELISA, Western Blot
• Synonyms: EphA4, Antibody; EphA4 (Tyr-602)[conserved site], phospho-specific Antibody; EphA4 (Tyr-602))[conserved site], phospho-specific; EphA4 602; anti-EphA4 antibody

• Host: Rabbit
• Reactivity: Human, Rat, Mouse, Chicken
• Clonality: Polyclonal
• Specificity: This antibody was cross-adsorbed to unrelated phosphotyrosine peptides before affinity purification using EphA4 (Tyr-602) peptide. The purified antibody detects a 120kDa* band corresponding to EphA4 in Western blots of HUVEC cells treated with pervanadate and in mouse brain tissue.
• Form/Format: Rabbit polyclonal, affinity-purified antibody is supplied in 100ul phosphate-buffered saline, 50% glycerol, 1mg/ml BSA, and 0.05% sodium azide.

• Applicable Applications for anti-EphA4 antibody: IHC (Immunohistochemistry), ELISA, WB (Western Blot)
• Immunogen: EphA4 (Tyr-602) synthetic peptide (coupled to carrier protein) corresponds to amino acids surrounding phosphorylated tyrosine 602 in human EphA4. This sequence has significant homology to the conserved site in rat and mouse EphA4, and is conserved well in most other EphA and EphB family members.
• Preparation and Storage: Store at -20 degree C. Stable for 1 year.

WB (Western Blot)

(Western blot analysis of humanuMbilical vein endothelial cells untreated (lanes 1, 3, 5, & 7) or treated with pervanadate (1mM) for 30 min. (lanes 2, 4, 6, & 8). The blot was probed with anti-EphA4 (N-terminal region) (lanes 1 & 2), anti-EphA4 (Tyr-779) (lanes 3 & 4), anti-EphA4 (Tyr-602) (lanes 5 & 6), or anti-EphA4 (C-terminal region) (lanes 7 & 8).)

IHC (Immunohistochemistry)

(Paraformaldehyde-fixed zebrafish embryos were probed with anti-EphA4 (Tyr-602) (EP2731) then detected using Alexa Fluor 647 goat anti-rabbit. Arrows show labeling of somite boundaries and the notochord. (Image provided by Dr. Scott Holley at the Department of Molecular, Cellular and Developmental Biology, Yale University.))

The EpHfamily of Receptor tyrosine kinases and their Ephrin ligands are important for cell positioning and morphogenesis during development. EpHreceptors are classified into 10 EphA and 6 EphB receptors, which preferentially bind to the type A and type B ephrins, respectively. The EphA4 receptor can inhibit axon outgrowth and has roles in regulating axon projections during neural development. EphA4 signaling pathways require its kinase activity and involve binding and activation of Rho-GTPase guanine nucleotide-exchange factors (GEFs). EphA4 activation leads autophosphorylation of Tyr-596 and Tyr-602, and the conserved sites in EphA2 are required for binding to the GEFs, Vav2 and Vav3, and ephrin-induced cell migration. The Tyr-779 site in the kinase domain is also phosphorylated in vivo and may regulate kinase activity. Activated EphA4 leads to Src kinase phosphorylation of the GEF, ephexin-1, and this activates RhoA. Thus, EphA4 signaling involves complex tyrosine phosphorylation in its cytoplasmic region along with interaction with several GEFs.
